Swain’s Cut Bridge carries NC 906 across the Atlantic Intracoastal Waterway (ICW) connecting Oak Island, NC to the mainland. Built for $36 million under contract to the North Carolina Department of Transportation, the bridge opened for traffic in the fall of 2010. A high rise design similar to the Barbee Bridge which crosses the ICW at the east end of the island, the Swain's Cut Bridge is built over a narrow part of the channel and required only three main spans while the Barbee Bridge needed 37.
